Sorted! Turns out the Mopar instructions supplied are wrong. They don't agree with what is in the Becker 6810 manual and after disconnecting the mute wire from the speed sense wire (yes you read it right, as per Mopar instructions). All is now fine with the Sat/Nav/Handsfree. Quite pleased with the parrot 3000 evo as well. It works very well even at 45 - 50 mph with the top down which is really good for voice activated!!!

Looks like I have the issue with the hesitation nailed as well, this could be linked to the pre-ignition...will update when I know.

Still looking for UK TMC codes for the ITIS system on Navteq for the Becker DTM High Speed if anyone has any leads I'd appreciate it.

Thanks again.
